does she suffer from autism?

Yes, many autistic people are capable of wearing make up and eye lenses and dyeing their hair and stuff. I definitely dyed my hair when I was a teen. Couldn't wear lenses though - my eyes are too dry (I have eczema and the optometrist says I also have the eczema on my eyes - you just don't see it, but it makes my eyes too dry for lenses).

So, is it possible for her to be autistic? Yes. But it's more likely that she just has some form of social anxiety. Social anxiety is much more common than autism, and could lead to the behavior you described just fine. Nothing you said gave any indication that she'd be autistic rather than just have social anxiety. It's also possible she has been abused or bullied a lot and doesn't interact normally because of that.

there's no longer something definitive on the subject of Cho having autism. I study that article too and it sounds to me like the media is grasping at straws with out having each and every of the info. i'm no longer asserting that is not achieveable, I do exactly no longer think of that is probable. experts have suggested he in good shape the profile for this style of killer.......think of decrease back to Columbine. no person ever suggested those young ones had autism.

Autism is a mental illness that makes people be too organised in their everyday routines. This girl is too shy, or she wants to be alone or she demands very special friends
